Saint Matthew Chapter 17: 1-9
And after six days Jesus took with him Peter and James and John his brother, and led them up a high mountain apart. And he was transfigured before them, and his face shone like the sun, and his garments became white as light. Moses and Elijah, talking with him. And Peter said to Jesus, "Lord, it is well that we are here; if you wish, I will make three booths here, one for you and one for Moses and one for Elijah." He was still speaking, when lo, a bright cloud overshadow them, and a voice from the cloud said, This is my beloved Son, with whom I am well pleased listen him." When the disciples heard this, they fell on their faces, and were filled with with awe. But Jesus came and touched them saying, "Rise, and have no fear,"
And when they lifted up their eyes, they saw no one but Jesus only. And as they were coming down the mountain, Jesus commanded them, "Tell no one the vision, until the Son of man is raised from the dead.
